That is totally normal for a 60cm sized 80 GHz (well, FDD, optimized 71 to 86 GHz) antenna, such as the Radiowaves 60cm/2' dishes.
Yes they really are a half degree beam width but they're not that hard to aim, the maximum distance you'll ever build a link is at 3.5 to 4km. If you can teach green rooftop/tower guys how to aim these, they can aim anything. Guys who've never seen an 11 or 18 GHz link before will have a really easy time.
